WHAT SHOULD BE PROCESSED FOR DNA?

WHAT SHOULD BE PROCESSED FOR DNA?

• A. CLOTHES
• B. ANYTHING THE VICTIM TOUCHED
• C. WHERE THE CRIME HAPPENED/GEOLOGICAL LOCATION
• D. VICTIM BODY & SUSPECT BODY

Answer: (B)

DNA can be recovered from items a person has touched because people leave tiny cells and other biological material on objects when they handle them. These touch DNA traces can persist on surfaces like doorknobs, cups, clothing, or weapons, providing a genetic link to the person who handled them. Because of this, processing anything the victim touched gives the best chance of finding usable DNA evidence that could help identify or connect someone to the scene. Other sources, like the crime scene location or the bodies, can contain DNA but are not as universally informative for establishing connections through everyday contact. Items the victim interacted with are especially valuable because they are direct points of contact where DNA transfer is most likely to occur.
